The BART to Silicon Valley - Extension to San Jose and Santa Clara extension project (Phase II) is the proposed second phase of a two-phased BART extension from the current BART terminus in Fremont, CA, to Santa Clara, CA. The first phase of the project (Phase I) extends BART 10-miles from the existing Fremont Station south to two new stations (Warm Springs and Berryessa Stations). Phase II of the project will extend BART an additional 6 miles from the Berryessa Station south into San Jose and Santa Clara. Phase II of the project proposes include four stations. 

The project corridor will connect San Francisco Bay Area's heavily urbanized East Bay with the equally-populated South Bay. Development in the East Bay, including Fremont (population 218,100) and Milpitas (population 71,600) is constrained geographically by the San Francisco Bay on the west and Diablo foothills on the east. Development in the South Bay extends the width of Santa Clara Valley. San Jose (population 1,023,100) occupies the east and central portion of the Valley, which is in Santa Clara County (population 1,880,900). The area from north San Jose into southern San Mateo County on the west side of San Francisco Bay is the heart of Silicon Valley, although as a result of continuing growth over the last 20 years, Silicon Valley has expanded to include Milpitas and southern Alameda County, which are served directly by BART Silicon Valley.

Both Santa Clara County and the project corridor are anticipated to continue their remarkable growth well into the future. Regional projections by the Association of Bay Area Governments (ABAG) indicate that in the 30-year period from 2005 to 2035, the county’s population will increase by approximately 679,700 people, while households will increase by 210,500, and the county will see jobs increase by 492,900. Project corridor population will increase by approximately 91,000 people, households by 27,000, and jobs by 84,000 within the same period. Jobs will grow faster than households, exacerbating the jobs-housing imbalance and the need for workers to commute longer distances.
